TestPathHelper signature change causing issue on JBeret ecosystem CI

The innocuous-looking change in #46625 is causing an issue running the JBatch TCK: https://github.com/quarkiverse/quarkus-jberet/actions/runs/13757259497

With:

This actually affects all tests which are packaged in jars before running.
